Keragaman Stomata Okra (Abelmoschus esculentus L. (Moench)

Abstract

Okra (Abelmoschus esculentus L. (Moench.) is high nutrition compound potential for diabetes and Alzheimer. Yield is one of the characters have to improve in plant breeding program through stomata characterization. The variability for 14 genotypes showed significantly for stomatal length, stomatal width, epidermal cell number, chloroplast number, stomatal number, stomatal index and stomatal density. Stomatal density for P2 was  256.80 mm2 that was nonsignificant with Zahira (265.31 mm2) and Naila (204.08 mm2). Genotypes P2, Zahira and Naila showed low stomatal density that mean efficiency for water management in leaves. The high stomatal index causing high photosynthesis and high yield. Stomatal index were high for genotypes P1 (40.31) and P2 (35.69). Naila has low stomatal index but Zahira as significant as genotype P2. Zahira could be high yield genotype candidate.Keyword : candidate, density, index, genotype
